What grass is this

I have this grass growing in my front yard. Our lawn, when we moved here 6 months ago was, and still is full of crabgrass and weeds and rough grass. I found this in the back yard and thought it wold be great for the front yard so put some in a vacant area. It is a clumping grass and is about 12“ tall. I was hopeful that it would be short enough to let it grow and cover the whole lawn area. For me 12” is a great height but for my husband and particularly for the neighbors it is too tall.

Can anyone tell me what it is and if it’s a keeper or a thug to be disposed.

Looks like green kyllinga. It's a member of the sedge family and not a grass. Thus if you wanted to kill it, grass killers won't touch it. You would need a sedge killer like Sedge Hammer, Image, or I believe there's another one.

Green kyllinga looks like nutgrass, also a sedge, but GK will survive with almost no water for seasons and seasons. Nutgrass needs plenty of water to thrive and can be killed back by withholding water.
